Rack & Pinion Cradle System
Thank you for your interest in Flaming River products. We hope you enjoy your rack and pinion cradle
system.
The product that you have selected has been built and designed for improved driving comfort and
convenience. No drilling welding or grinding is necessary.
All systems have been created on stock chassis with little or no change to the original suspension, engine,
or transmission.
Quality grade fasteners and materials are used to allow normal installation. We do recommend new outer
tie rod ends and a professional alignment.
Thanks again,
Jeanette Ladina

Installation of the Flaming River Rack and Cradle
1) Install the rack and pinion cradle by sliding it into place between the frame rails, installing the new
hardware using three 7/16” bolts where the gear box was mounted and two 3/8” bolts where the idler
arm was located. Tighten the 7/16” nuts and bolts to 50-65 ft lbs and the 3/8” nuts and bolts to 40 -45
ft lbs.

3) Install the OEM adjuster sleeves onto the new Flaming River inner tie rod ends, next install the outer
tie rod ends into the adjuster sleeves and adjust tie rods until the original zerk to zerk measurement
taken before disassembly is obtained. Measurement from the index page.
4) To install the outer tie rod ends into the spindles you must load the front suspension. (Securely placing
jack stands under the lower control arms and lowering the car onto the jack stands accomplishes this.)
Install the outer tie rod ends into the spindle and tighten the castle nuts to 30-40 ft lbs. Make sure to
install cotter pins into the castle nut and tie rod end and bend the tabs over for security.

length of the shafts.
3) Install your shaft kit and snug each set screw so that it will leave a mark in the shafts.
4) Remove shaft and dimple each setscrew mark using a ¼” drill bit. (As shown below.)
